Here it is, in its blinky glory . So here’s the story, pandemic aside, I actually built one of these @ defcon 23. Disappointed in the record badge, Thursday night I went to my room and built a version not so different from this one. So when TDI went virtual, I figured I’d take a one-off badge “Off the Shelf”
This is not a comprehensive set of instructions for assembling this, but rather a set of quick reference charts.
